BUTTER-WORKING CHURN.

SPECIFICATION forming part of Letters Patent 1&0. 787,408, dated April 18, 1905.

Application filed April 13, 1903. Serial No. 152,336.

.be it known that l, DANIEL A. Srmonn, of Poland. in the county of Herkimer and State of New York. have invented certain new and useful Improvements in Butter orking hurns: and I do hereby declare that the following is a full, clear. and exactdescription of the invention, which will enable others skilled in the art to which it appertains to makeand use the same, reference being bad to the accompanying drawings, and to the numerals of reference marked thereon, which form part of this specification.

The object of my invention is to provide a lmtter-working churn which is simple in its construction and eiiective in operation and adapted for use either as small hand devices or for large power devices.

In the drawings, Figure 1 shows a side elevation of the churn and butter-worker as the same is constructed for a small hand-machine. Fig. .2 shows an end view of the same. Fig. 3 shows a horizontal section of the barrel in connection with the parts below the sectionline. Fig.4: shows a vertical section of the churn with the barrel in its upright position and the opening end at the top. Fig. 5 shows a vertical section taken at right angles to the section on which Fig. 1 is taken in connection with the working parts shown in side elevation. Fig. 6 shows a section similar to Fig. l with the churn-barrel in inverted position from that shown in Fig. 1. Fig. 7 shows a similar view to Fig. 6 with the working parts adjusted to a difi'erent position. Figs. 8 and I 9 show details of the stationary crank mechanism employed in the construction.

Referring to the reference-numerals in a more particular description, 1 indicates a frame which supports the barrel or receptacle 2 on trunnions in uprights, so that the barrel is adapted to revolve end over end. To one of the bearings or trunnions, 3, there is attached in the construction, as shown, a crank 1, by means of which the barrel may be revolved. Other mechanism for applying power than the crank may be provided. The other bearing or trunnion, 5, is hollow, and passing through the opening in the same is one branch of the stationary crank part 6. The

part 6 consists of a swinging arm portion 6 and a spindle portion 6", which extends through the opening in the bearing 5 and is provided at its inner end with a tenon 6 or its equivalent for coupling it to the other portion 7 of the stationary crank. The other end of the stationary crank portion 7 is provided with a bearing 7, which engages in a socket on the inner side of the barrel in alinement with the bearing 3. The stationary crank 8 is formed in the part 7 as the construction is shown. The arm 6 extends on the outside of the supporting-frame and is provided with means for securing it against revolution with the barrel and to some extent adjusting the angle of the crank 8 with reference to the position of the frame. This mechanism, as shown, consists of a swinging lever 10, pivoted at 10 on one of the standards of the frame, provided with a handle 10 on one end, by means of which it may be operated, and having a projection 10", adapted to strike suitable stops 1 on the frame and limit the swinging operation at substantially a horizontal position in either direction. The opposite end of the lever 10 from the handle 10 is connected by a connecting-rod 11 with the swinging end of the arm (5. By turning the handle 10 in the direction shown by the curved broken line in Fig. 2 the arm 6 is swung from the position shown in full lines in Fig. 2 to that shown in dotted lines in the same figure.

Hinged on one side of the barrel adjacent to the bottom on a bar 12 or other suitable device is the worker 13. In order to make the worker readily detachable from this pivotal bar 12 in order to remove it from the churn, the same is provided with a groove in its upper surface, which receives the underside of the bar 12, and it is held in position by a button 1%, which can be turned to release the worker. The worker 13 is of a somewhat less area than the bottom of the churn and is preferably formed in such a way as to leave the open space a between the free working edge of the worker and the opposite side of the churn. The free edge of the worker 13 is connected with the stationary crank 8 by means of a connecting-rod 15.

The connecting-rod engages the crank 8, preferably by means of a hook, as shown, and is secured in engagement by a button 16, which may be turned to release the connecting-rod therefrom, so that the connecting-rod and worker can be removed from the barrel.

The upper end of the barrel is provided with a removable cover 18 and with some clamping means, as 19, by means of which it can be secured in position on the churn.

A tap-hole 20 is provided near the bottom of the churn, closed by a cork or other suitable means when not in use.

In operation the churn is filled about onethird full or a little more -not exceeding .halfwith cream while the cover is removed.

When filled, the cover is applied and secured, and the churning is accomplished by revolving the churn by means of the handle or other operating mechanism. The churn should be revolved in the direction indicated by the arrows in Figs. 4, 6, and 7. During the churning operation the stationary crank 8 will preferably be adjusted to the position shown in Fig. 7. The churning operation of course consists in carrying the cream up as the churn swings over and spilling or pouring into the lower end of the churn. After the butter has come the buttermilk will preferably be drawn off through the tap-hole 20 and a quantity of cold water introduced. The butter-working will then take place by revolving the churn the same as before described. As the churn revolves from the position shown in Fig. 4 toward that shown in Fig. 6 the butter will be caught between the open edge of the worker and the bottom and carried upwardly, and as the churn attains its inverted position the lump of butter will be squeezed against the bottom. Immediately after the churn passes the inverted position the worker will be withdrawn from the bottom and the butter will slide out and drop into the bottom of the churn and be caught on the next revolution, as before described, and again squeezed against the bottom. During the butter-working operation the stationary crank 8 will preferably be adjusted to its vertical position, as shown in Figs. 5 and 6. When the working is completed, the washwater can be drawn out through the tap-hole 20, and after the cover is removed the butter can be dumped out through the open top into a suitable receptacle to receive it by inverting the churn.

By operating the buttons 14 and 16 the butter-worker, with its connecting-rod, may be easily removed from the churn, and by disconnecting the arm 6 from its adjusting mechanism the part 6 can be removed, and after that is removed the crank part 7 can be removed from the churn. This will leave the churn simplya plain barrel. The parts likewise can be replaced by performing the operations in the reversed order.

It is evident that numerous modifications and changes in and from the construction described may be made without departing from the spirit of my invention.

What I claim as new, and desire to secure by Letters Patent, is

1. A butter-working churn consisting of a barrel mounted on bearings to rotate end over end, a worker pivoted adjacent to the bottom of the barrel at one side and free to swing at the other, a stationary crank within the barrel, a connecting-rod between the swinging edge of the worker and the stationary crank, substantially as set forth.

2. A butter-working churn consisting of a barrel mounted on bearings to rotate end over end, a worker pivoted adjacent to the bottom of the barrel at one side and free to swing at the other, a stationary crank within the barrel, a connecting-rod between the crank and the swinging edge of the worker and means for adjusting the position of the stationary crank, substantially as set forth.

3. A butter-working churn, consisting of a barrel mounted on bearings to rotate end over end, a worker movable toward and from the end or head of the barrel, astationary crank arranged within the barrel and a connection between the worker and the crank, substantially as set forth.

4. The combination in a churn and butterworker of a rotary churn-barrel, a worker movable toward and from the interior surface of the barrel, a stationary crank within the barrel and a connection between the crank and worker, substantially as set forth.

5. A combined churn and butter-worker having a rotary barrel, a worker located in the barrel and pivoted at one edge, a stationary crank within the barrel and a connection between the movable edge of the worker and the stationary crank, substantially as set forth.

In Witness whereof I have afiixed my signature, in presence of two witnesses, this 6th day of April, 1903.

DANIEL A. SPRAGUE.
